Product Overview & System Integration

This 51.2V 200Ah Energy Storage battery module serves as a primary power bank for residential self-consumption and light commercial microgrids. Engineered with a 16S LiFePO4 configuration, the unit provides 10.24 kWh of usable energy, capable of parallel scaling up to 163.8 kWh total capacity. The internal hardware interfaces with major hybrid solar inverters via standard CAN/RS485 protocols. Our Xiamen factory provides full technical support for custom PCB communication mapping, chassis metal stamping, and specialized terminal layout to match existing cabinet configurations. Engineering teams offer direct system integration consultations for projects involving specific voltage threshold requirements.

Quality Control & Global Standards

Operations adhere to strict ISO 9001 standards. Each module undergoes a four-stage verification process: laser welding depth analysis, static cell voltage grading, 100% automated BMS function logging, and 24-hour thermal cycle aging under load. Final production batches are validated for international compliance, including TUV, CE, and RoHS. All export units carry UN38.3 certification and MSDS documentation required for Class 9 hazardous material handling. Factory-level testing ensures every unit meets internal resistance tolerances below 0.5 mΩ per cell block to prevent thermal runaway.

Packaging & Logistics Safety

Export logistics utilize specialized Class 9 (UN3480) dangerous goods handling protocols. Each unit is secured in high-density EPE foam shock-absorption packaging and placed inside 7-layer double-wall corrugated cartons. Bulk shipments are stacked on fumigation-free wooden pallets, wrapped in heavy-duty stretch film, and cross-strapped with tension-rated bands. Container-bound pallets are reinforced with timber bracing and dunnage bags to ensure mechanical stability during heavy-sea transit.

◎Telecommunications Back-up: Deploying 51.2V 200Ah units for high-reliability energy reserve in remote 5G cellular transceiver sites.

◎Mobile Utility Power: Used in specialized outdoor broadcasting trucks and mobile solar-powered work-site containers.

FAQ

Q: How does the battery communicate with non-standard proprietary inverter protocols?

A: Our factory BMS supports firmware-level adaptation. We provide a custom communication toolset and protocol conversion mapping for projects utilizing non-standard CAN/RS485 registers. Once your engineering team provides the inverter's communication data sheet, our technicians perform the necessary firmware adjustments during the pre-production phase.

Q: Does the cycle life performance remain consistent if the battery is utilized in fluctuating desert temperatures?

A: The system maintains 80% capacity at 6000 cycles under controlled 25°C conditions. In extreme desert heat (above 40°C), BMS-controlled derating protects internal cells. For permanent high-ambient-temperature installations, we recommend configuring the cabinet with external active cooling, which our manufacturing team can pre-install at the factory.

Q: What is the typical production timeline for an OEM project requiring custom branding and color-matched cabinets?

A: Logo laser-etching and standard color powder coating for batches require 7-10 working days. If a custom enclosure design or specific terminal layout is requested, the mold development and pilot run period is 20-25 days. Production schedule priority is provided for EPC contracts with verified delivery timelines.
